11 Claims.

The present invention relates to a machine for applying bindings to ahollow thread package or cop, and is intended primarily for use in tyingbinding strings around cakes of artificial silk thread which have beenformed in accordance with the so-called pot spinning method ofmanufacture of artificial silk, allowed to age, and then wrappedpreparatory to subsequent processing operations, as illustrated, forinstance, in the patent to Lockhart No. 1,904,377, dated April 18, 1933,for the manufacture of artificial silk. The binding strings are passedthrough and around the thread package, and serve the dual purpose ofholding the wrapping in place, and of supporting the walls of thepackage to prevent displacement or undue separation of the threadwindings during subsequent handling and processing operations on thepackage. In order to allow for subsequent expansion or spreading of thecake wall during the processing operations, and more particularly duringthe preceding mechanical operation of breaking down the cake wall toloosen and expand the cake as set forth in the pending application ofLockhart, Serial No. 647,368, filed December 15, 1932, now matured intoPatent No. 2,012,723, dated August 27,

1935 for a method of producing threads of arti-.

ficial silk, the length of the bindings must be carefully measured toallow for this expansion, and then to give to the wrapped package therequisite amount of support in its expanded form.

It is a principal object of the present invention to provide a machinewhich embodies a binding and knot tying mechanism in combination with aconveyer mechanism which is adapted to present thread packages rapidlyand efficiently to the knot tying mechanism to place a series ofbindings around the walls of each package.

It is more specifically an object of the invention to provide a machinefor placing a plurality of bindings around a cake of artificial silkthread which will be of a suitable length and properly placed to affordan adequate support for the cake during subsequent processing operationsperformed thereon.

It is a further object of the invention to provide in a machine of thisdescription a conveyer mechanism which is particularly well adapted forcontinuous operation to present a continuous series of thread packagestothe binding and knot *tyingmechanism with a minimum of attention fromthe operator to secure a continuous and efficient operation of themachine.

With these and other objects in view, as may hereinafter appear, aprincipal feature of the invention consists in the provision of abinding and knot tying mechanism in combination with the carriermechanism adapted to present a series of hollow thread packages theretofor tying a number of bindings around the walls of each package, incombination with a loading conveyer for positioning the packagessuccessively on the carrier, and a discharge conveyer for disposing ofthe packages at the end of the binding and knot tying operation.

Another feature of the present invention, consists in the combinationwith a plurality of binding and knot tying mechanisms, of carriermechanism which is arranged to position hollow packages successivelywith relation to each knot tying mechanism to tie bindings aroundopposite walls of each package, and for varying the position of eachpackage with relation to each successive binding and knot tyingmechanism to secure a relatively large number of bindings spaced aroundthe package wall. I

The several features of the present invention consist also in thedevices, combinations and arrangement of parts hereinafter described andclaimed, which together with the advantages to be obtained thereby willbe readily understood by one skilled in the art from the followingdescription taken in connection with the accompanying drawings, inwhich: Fig. 1 is a general view in side elevation of a machine embodyingin a preferred form the several features of the invention; Fig. 2 is aplan view of the machine illustrated in Fig. 1; Fig. 3 is an enlargeddeniil view of the binding and knot tying mechanisms and carrierillustrated in Fig. 1; Fig. 4 is a sectional view on an enlarged scaletaken on the line 4-4 of Fig. 3, illustrating particularly the controlmechanism including a turn-table for turning the cake throughsubstantially a right angle on the carrier; Fig. 5 is a plan view of theparts shown in Fig. 3; Figs. 6, 7 and 8 are a series of more or lessdiagrammatic views showing the mode of operation of one of the bindingand knot tying mechanisms to place a binding around one wall of thepackage; Fig. 9 is a detail view of the timing gears for controlling theoperation of the mechanism for releasing and turning the cake; Fig. 10is a detail view of the timing gears for controlling the rotationalmovements of the table on which the cake is turned; and Fig. 11 is adetail view of the cam for raising the turntable into operatingposition.

The machine herein disclosed as embodying in a preferred form theseveral features of the present invention, comprises two binding andknot tying mechanisms or hines ofwell known design in combination with aconveyer mechanism to feed packages successively to each of the bindingand knot tying mechanisms to place a number of bindings in spacedrelationship around the walls of each package. Each of the binding andknot tying machines referred to, comprises a looper arm which isnormally held in a raised position above the path of movement of thepackage, and through which a thread is passed to a knot tying devicelocated beneath the line of travel of the package. As a package is movedinto operative position, a trip device operates to cause the looper armto be moved downwardly into operative engagement with the knot tyingdevice, so that a loop of thread is passed around the package wall,knotted, cut, and the looper arm again raised leaving thethread endengaged by the knot tying device preparatory for the next succeedingoperation.

' The conveyer mechanism for presenting packages successively to thebinding and knot tying mechanisms comprises a loading conveyer, anendless carrier cooperating therewith having a series of grippers whichare arranged to take the packages successivelyv from the conveyer andpresent them in operative position to the binding and knot tyingmechanism, a receiving conveyer onto which the packages are deposited bythe grippers at the end of the binding and knot tying operation, and adischarge conveyer. In order to secure a relatively large number ofbindings around each package, mechanism is provided for turning eachpackage through substantially a right angle on the carrier prior to theoperation of the second of the binding and knot tying mechanisms abovedescribed. This mechanism comprises a turn-table located in the path ofthe carrier between the two knot tying mechanisms, and a controlmechanism which acts when rendered operative to actuate the cooperatinggrippers to place a package on the turn-table to turn the table and thepackage supported thereon through substantially a right angle, andthereafter to reengage the grippers. The carrier machanism is operatedthrough a driving mechanism which isarranged to provide a dwell in theadvance of the grippers and packages supported thereon at predeterminedintervals for the operation of each of the binding and knot tyingmechanisms and the turn-table.

Referring more specifically to the drawings, the carrier mechanism forfeeding hollowpackages of thread successively into operative position inthe machine, comprises two similar endless sprocket chains 28 which aresupported in parallel relationship on identical sprockets 24 secured toa shaft 28 journalled in bearings 28 carried on a separate frame 88, andon identical sprockets 32 mounted on a drive shaft 84 which is supportedto turn in bearings on a frame 88. Secured ,to each sprocket chain is aseries of gripper units which are mounted exactly opposite each other inspaced relationship around the entire length of each sprocket chain.Each gripper unit, as best shown in Figs. 4 and 5, comprises a block 88which is secured at its base to the chain 28 and is provided with alaterally extending bore to receive a plunger 48. A compression spring42 coiled around a reduced portion of the plunger within the bore, andseated at one end against a shoulder 44 in the block, and at its otherend against a shoulder 48 formed on the plunger tends to maintain theplunger normally in an advanced position. A collar 48-secured to therear end of the plunger is arranged to engage with the rear side of theblock to limit the advancing movement of the plunger 48 under thepressure of its spring 42. Secured to the forward end of the plunger 48is a gripper member comprising a curved plate 58 which is arrangedforgripping engagement with the thread package, and is provided with a hub82 which is sleeved onto the forward end of the plunger 48 and rigidlysecured thereto by means of a set screw 84. In order to accuratelyposition each gripper unit during its travel with the correspondingsprocket chain 28, a cross shaft 88 is mounted on each block 88, and isprovided at each end with rolls 88 and 88 adapted to ride respectivelyon rails 82 and 84 which are mounted at each side of the sprocket chainand extend parallel thereto along the length of its travel on the upperlevel. Each gripper unit is further supported against outward lateralmovement due to the gripper action 01120 the plunger 48 and spring 42 bymeans of a roll 88 which is mounted on a vertical post 88 formed on theblock 38, and is adapted for engagement with a similar rail 18 whichfollows the, path of the corresponding sprocket chain throughout itsentire length. In order to control the operation of each pair of gripperunits to move them into and out of operative position, there is securedto each plunger 48 a pin 12 which extends upwardly through a slot 14formed in the block 88, and is provided at its upper end with a cam roll18 which is adapted for engagement with a number of control cams duringthe travel of the gripper unit with the carrier chains 28 as hereinaftermore fully to be described.

Packages of thread are fed successively into position where they may betaken in turn by each succeeding pair of grippers by means of a loadingconveyer or belt which comprises a pair of sprocket chains "adapted toride over identical sprockets 88 secured to a shaft 82 mounted to turnin bearings on a frame 84, and over a pair of identical sprockets 88similarly secured to a shaft 88 mounted to turn in bearings on the frame88. The sprocket shaft 88 and sprockets 88 are mounted with relation tothe ,endless carrier sprocket chains 28, so that the sprocket chains 18of. the loading conveyer travel between and parallel to the carriersprockets 28 for a short distance before passing downwardly around thesprocket wheels 88. Mounted on the sprocket chain 18 are a series ofholders 88 spaced exactly the same distance apart as the gripper units88, so that each succeeding pair of grippers may be rendered operativeto engage with the thread package positioned on the next succeedingholder. The loading conveyer is driven in synchronism at the same rateof travel with the carrier through driving connections which comprise asprocket chain 92 (see Fig. 3) which passes around sprockets 84 and 88mounted respectively on the shafts 88 and 28.

The operation of the grippers is controlled to enable the grippers toengage with and take the succeeding packages from the holders 88 on theloading conveyer by means of two similar stationary cams 88 which arearranged one adjacent each of the carrier chains 28 to engage with thecam rolls [8 respectively on each series of gripper units to retract theplungers 48 and gripper members 88 against the pressure of their springs42 as each succeeding pair of grippers reaches the end of the lower legof its travel on the carrier, so that the grippers will be maintained inretracted position as they rise onto the upper level, and are registeredwith relation to the holders 90 and packages supported thereon. Thecontinued advance of the gripper units then causes the cam rolls I6 toride oil the high portions of the two cams 98, permitting the grippersto come into yielding gripping engagement with the package supported onthe corresponding holder 90. As the advance of the carrier and theloading conveyer synchronized therewith is now continued, the holder 90moves downwardly around the sprockets 86, leaving each successivepackage in engagement with the corresponding gripper. With thisarrangement of parts it will readily be seen that the operator, byplacing a number of packages on the conveyer, can load the machine for arelatively long period of operation without further attention, thelength of this period being controlled only by the length of the loadingconveyer and the available number of holders mount- ,ed thereon on whichpackages may be mounted.

The present machine is also provided with a receiving conveyer which isgiven a step-by-step movement in synchronism with but at a slightlyfaster rate than the gripper units to receive the packages from thegrippers, and a discharge conveyer which is continuously driven and isarranged to discharge the cakes onto a discharge platform. The receivingconveyer comprises a belt I09 which is supported on two rollers II I andH3 in parallel relationship to and between the endless carrier chains20. The rollers I II and H3 are carried on rotatable shafts H and IIIrespectively, the shaft II5 being directly connected to turn with thedrive shaft 34 by means of a sprocket chain I I9 arranged to pass oversprockets on the shafts I I5 and.

The packages deposited on the receiving conveyer I09 are then deliveredonto a discharge conveyer which comprises a conveyer belt I I0 adaptedto ride over idler pulleys H2 and H4 and around a driving pulley II6. Anumber of cross pieces I22 are secured to the outer surface of theconveyer belt I I0 to engage with and prevent the slipping of thepackages as they are carried up the inclined surface between the drivingpulley H6 and the idler pulley II2 as indicated in Fig. 1. The drivingpulley H6 is continuously driven by means of an electric motor H8 and adriving pulley I20, as best shown in Fig. 1. As the cakes deposited onthe discharge conveyer IIO reach the top of the incline adjacent thepulley II2, they are transferred to a chute I24 which is provided withtwo alleys I26 to receive the finished packages, and a switch I28 whichserves to guide successive packages alternately to the one and then tothe other alley. The switch I28 is mounted to swing freely on a pivotI30 and is provided with a fish-tail I32 which is engaged by a packageand serves to swing the switch positively to its alternate position.

The operation of the grippers to deposit the finished packages on thereceiving conveyer I09 is controlled by means of two similar stationarycams I42 which are arranged one adjacent each end of the carrier chainsnear the end of the travel of the carrier on its upper level to engagewith the cam roll I6 respectively on each series of gripper units toretract the plungers 40 and gripper members 50 against the pressure ofthe springs 42 as each succeeding pair of grippers reaches the end ofthe upper leg of its travel on thecarrier to drop each successivepackage in turn onto the receiving conveyer. The cams I42 are shaped tomaintain the grippers in their retracted position as they are carriedaround the to the knot tying and gripping unit I52.

sprockets 82 to the lower level to insure clearance for the grippers asthey move downwardly below the level of the receiving conveyer beltI091.

The binding and knot tying mechanisms herein disclosed are commercialproducts which have been rebuilt and adapted for use in the presentmachine, and therefore will be described only so far as necessary toindicate their mode of operation in connection with the present machine.Each of these mechanisms comprises a casing I46 which is provided with alaterally extending hollow supporting arm I50 for a thread tying andgripping mechanism I52 of ordinary description which is located directlybeneath and in the line of movement of the packages through the machine.As an integral part of this mechanism there is also provided a looperI54 which is secured to a supporting rod I56 carried on two lever, armsI58 and I60 which are arranged to turn about the same axis, the leverarm I58 being pivotally mounted at I62 on the machine frame, and thelever arm I60 being secured to an actuating rock shaft housed within thecasing I46 and forming an integral part of the binding and knot tyingmachine.

Thread from which the bindings are made is drawn :from a spooldesignated at I64 on a support I66 mounted on the upper part of thecasing I46, is threaded through an eye in the end of the looper I54, andextends downwardly across the path of the advancing package to the knottying and gripping mechanism I52. The knot tying and gripping mechanismis tripped into operation to tie a binding around the package wall whenthe package has been moved into operative position by means of a tripmember I68 which is secured to a rock shaft I10 mounted transversely ofthe machine; and is provided with a curved tip which is arranged in thepath of the advancing package. The rock shaft I10 carries also a leverarm I12 which is connected by means of a link I14 to one arm of thebell-crank H6. The bellcrank I16 is in turn mounted on a rock shaft I18which is housed within the casing I46, and operates when rocked to trip,the knot tying and binding mechanism into operation.

The several steps in the knot tying. and binding mechanism are shown inFigs. 6, 7 and 8. As shown in Fig. 6, the thread package has been movedpast the trip member I60, causing the trip member to be liftedmomentarily to trip the knot tying and binding machine into operation.At

- this point it will be noted that the wall of the package about whichthe binding is to be tied has been brought substantially into engagementwith the thread extending from the looper down Fig. 7 shows thesubsequent operation of the lever arm I54 which moves downwardly intoengagement with the thread tying and gripping unit I52 to carry thelooper thread completely around the wall of the package. The details ofthe mechanisms for performing the subsequent operations of tyingtogether and cutting off the loop and the engagement of the severed endof the thread with the gripping mechanism, have not been illustratedinasmuch as the mechanisms for performing these operations are wellknown in the art, and do not specifically form part of the presentinvention. The looper arm I54 is then returned to its original position.The subsequent advance of the package causes the trip member I66 againto be lifted by engagement with the opposite wall of the package to tripthe knot tying and binding mechanism again into operation as illusingposition in the machine.

trated in Fig. 8, in order to place a binding around the opposite wallof the package.

Inasmuch as it is contemplated that the present machine will be utilizedto place bindings around wrapped cakes of artificial silk thread formedin accordance with the pot spinning method for subsequent processing inaccordance with the method set forth in the copending application ofGeorge R. Lockhart, Serial No. 647,368, filed December 15, 1932, it isdesirable to provide a loose fitting binding around the wall of the cakewhich will permit subsequent expansion of the cake during mechanicalworking and the subsequent processing, and will at the same time provideadequate support for the cake during the entire processing operation. Tothis end the knot tying and gripping unit I82 is positioned apredetermined distance beneath the line of travel of the package, sothat a relatively loose binding is formed as clearly illustrated in Fig.8.

In accordance with certain features of the present invention, a drive isprovided for advancing the carrier chains 20 and the gripper unitsassociated therewith, which is adapted to provide a dwell in the advanceof each of the packages at predetermined intervals for the operation ofthe binding and knot tying machines. and also to permit each package inturn to be turned through substantially a right angle on its support, ashereinafter to be more fully described, prior to the operation of thesecond binding and knot tying mechanism, so that four bindings may beplaced in spaced relationship around the walls of each package. Thedrive as shown particularly in Figs. 3 and 5, comprises a cam disk I80which is mounted on a drive shaft I82, and is provided with a peripheralcam groove I84 adapted for engagement with a series of rolls I88 mountedat spaced intervals on one face of a wheel I88 secured to the driveshaft 84 for the carrier sprocket chains 20. The peripheral cam grooveI84 is so shaped that each succeeding revolution of the drive shaft I82and cam disk I80, will cause the cam to engage with the next succeeding'roll I88, and rotate the wheel I88 and drive shaft 84 through adistance which will be exactly equal to the distance between adjacentrolls I88. The length of the advancing movement imparted to the endlesscarrier chains 20 and the packages supported thereby for each step, isequal to exactly one-half of the distance between two adjacent gripperunits, so that two advancing steps are required to place each succeedingpackage in an identical operat- The drive shaft I82 and cam disk I80 arecontinuously driven from an electric motor I80 through connections whichcomprise a sprocket chain I82 arranged to ride over a sprocket I84 onthe drive shaft I82, and over a sprocket I88 secured to a shaft I88. Theshaft I88 is connected-through a reduction gear unit of ordinarydescription mounted in a casing 200 to the armature shaft 202 of theelectric motor I88. With this arrangement of the parts it w 11 readilybe seen that a step-by-step advancing movement is imparted to thecarrier sprocket chains 20 with a dwell following each advancingmovement while the cam disk I completes its rotation through a completerevolution.

The mechanism for turning each succeeding package through substantiallya right angle on its support subsequent to the operation of the firstand prior to the operation of the second binding and knot tyingmechanism, comprises a turntable 2I0 which as best shown in Fig. 4, issecured to turn with a vertical shaft 2I2 which is Journalled in abracket 2 I4 forming an integral part of the machine frame. Theturn-table is controlled through mechanism which is arranged to operateduring the dwell in the operation of the carrier to raise the tum-table,to rotate it through substantially a right angle, and thereafter toagain lower the turn-table to the inoperative position shown in Fig. 4.As best shown in Figs. 3, 4, 5, 9, 10 and 11, the driving mechanism foroperating the turn-table comprises a driving gear 2I8 secured to one endof the continuously rotating shaft I82, and arranged to mesh with a gear2I8 secured to a stub shaft 220. The gear M8 is provided throughsubstantially half of its periphery with a dwell (Fig. 9) surface 222which is arranged to engage with a corresponding dwell surface 224 onthe driven gear 2 I8. With this arrangement of the gears, the drivengear 2 I 8 is rotated only during the dwell in the advance of thecarrier chains 20, and is maintained in stationary position during theremainder of the rotation of the gear 2I8 with the drive shaft I82 whilethe carrier and packages supported thereon are being advanced to thenext succeeding dwell position. The drive is taken from the shaft 220through a link 228 which is joined through universal connections to astub shaft 228 which carries a bevel gear 280 arranged to mesh with acorresponding bevel gear 282 secured to a vertical shaft 284 mounted atone side of the machine.

- The shaft 284 is in turn connected to a laterally extending shaft 288through the bevel gears 288 and 240. Each succeeding revolution of thelaterally extending shaft 288 through the connections above described,is arranged to impart a 90 turn to the turn-table 2I0 through a gear 242on the supporting spindle 2I2 for the turn-table, and a gear 244 meshingtherewith supported on a vertical stub shaft 248 which also carries abevel gear 248 arranged to mesh with a bevel gear 288 on the drive shaft288. The driving gear 244 is provided with a dwell surface 252 whichextends around substantially of its periphery, and is arranged tocooperate with corresponding dwell surfaces 284 formed on a driven gear242, these parts being arranged so that for substantially three-fourthsof a complete revolution of the drive shaft 288 and driving gear 244,the gear 242 and turn-table 2I0 will be maintained in a stationaryposition, and will be advanced through substantially 90 during theremaining movement of the driving gear 244 through a completerevolution.

There is also secured to the end of-the drive shaft 288, an eccentriccam 288 which is adapted for engagement in a groove 288 formed in asleeve 280 rigidly secured to the turn-table spindle 2I2, so that foreach revolution of the drive shaft 288, the turn-table will be raisedinto operating position, and then returned again to the retractedposition shown in Fig. 4. A compression spring 282 coiled about thelower end of the spindle 2I2 between a collar 284 secured to the endthereof and the bracket 2, tends to maintain the spindle 2I2 andturn-table in a retracted inoperative position.

In order to make the turn-table operative to turn each successivepackage through substantially a right angle, it is necessary prior tothe rotation of the turn-table to cause the gripper units whilepositioned with a package directly over the turn-table, to release thepackageso that it may be turned with the turn-table, and

thereafter to again engage the package for the subsequent advancingmovements into operative relationship to the second binding and knottying mechanism. To this end a cross shaft 266 is mounted in the machineframe above the line of travel of the packages through the machine, andis provided with two face cams 268 which are arranged for engagementrespectively with the cam rolls 16 of the corresponding gripper unitswhen located in position with the package held thereby directly over theturn-table. The shaft 266 and face cams 268 are drivenin relation to theoperation of the turn-table by means of meshing bevel gears 216 and 212mounted re spectively on the cross shaft 266 and the vertical driveshaft 234.

In the operation of the machine, the mechanism for unclamping, turningand again clamping a cake is put into operation with each successiveadvancing step of the gripper units. However, inasmuch as two of theseadvancing movements are required to bring each successive cake intooperating position over the turn-table with the rollers 16 in positionto be engaged by the cams 266 to release a cake from the grippers 56, itwill be understood that each alternate cycle of movements of the caketurning devices is a dummy operation, and may be wholly disregarded.

During the rotation of the drive shaft I82 and cam disk I80 throughsubstantially one-half of a revolution, the carrier chains 20 andpackages supported thereon are advanced through one step. At this timethe gear 2| 8 is maintained in a stationary position through theengagement of its dwell surface 224 with the dwell surface 222 of thedriving gear 2I6 secured to the drive shaft I82. During the subsequenthalf of the revolution of the drive shaft I82, the carrier is maintainedin a rest position while the gear 2l8 and drive shafts 234, 236 and 266connected thereto are turned through a complete revolution to performthe operation of turning the package which will be assumed to have beenpositioned over the turn-table, through a right angle. The steps of thisoperation take place as follows:--First, the turn-table is moved to itsraised operative position by the operation of the eccentric cam 256, andthe plungers 40 and gripper members 50 are then retracted by theengagement of the high portion of the face cams 268 with the cam rollsI6 to release the package which is now supported solely by theturn-table. The turn-table is then given its 90 rotation by theengagement of the corresponding toothed portions I of the driving gear244 and driven gear 242. As the turning movement of the turn-table iscompleted, the plungers 40 and grippers 50 are again permitted toadvance under the pressure of their springs 42 as the cam rolls 16 againride off the high portions of the face cams 266, and finally theturntable is again brought to its low position by the operation of thecompression spring 262. It will be understood that the turn-table israised and lowered during its operation in order to prevent chafing ofthe cake by rubbing on a fixed surface. Length of bindings placed aroundthe package is controlled by adjustment lengthwise of the machine, ofthe position of the knot tyer;moving the knot tyer nearer the feed endlengthens the tie.

While the invention as herein disclosed has been illustrated inconnection with a machine which is particularly adapted for tyingbindings around four sides of a package of artificial silk threadsformed in accordance with the pot spinning method of manufacture, andwrapped preparatory for subsequent processing operations of the cake, itwill be understood that the machine is.

equally well adapted for placing bindings around hollow thread packagesof other types, .and that the several features of invention are clearlynot limited to the specific machine herein disclosed, but are capable ofbroader application to a machine employing the general organizationdescribed for placing bindings around other types of hollow threadpackages.
